TENSION DEVICE AND BOBBIN-SUPPORT FOR SPOOLERS.

Application filed July 7, 1916. Serial No. 108,063.

the bobbins from which the yarn is unwound,

upon their sides in open troughs, the bobbins revolving rapidly as the yarn is un- .wound. Ob ect1ons were discovered to this method of supporting the bobbins and the later practice has been to mount the bobbin vertically upon a dead spindle or support. the yarn being unwound from the end of the bobbin without rotation thereof.

One object of my invention is to provide an improved construction of bobbin support by the use of which the bobbin may be more easily inserted and removed. \Vith this object in view, one feature of my inven tion relates to a bobbin support manually movable from normal position, but returning automatically to such position when released. A second object of myv invention is to provide for convenientadjustment of the bobbin support and the tension mechanism as a unit relative to the spooler spindle.

For the attainment of this object I provide a separate bracket for each bobbin support and its corresponding tension mechanism. These brackets are clamped to a supporting bar and the parts oneach bracket may be adjusted as a unit along said bar. The specific tension mechanism and the cooperative position and relation between the tension mechanism and the bobbin support are not claimed herein as they form the sub ject matter of a divisional application. Se rial No. 4t3i3,082, filed December 27, 1920.

My invention further relates to certain arrangements and combinations of parts which will be hereinafter described and more particularly pointed out in the appended claims.

Specification of Letters Patent.-

Patented Jan. 4:, 1921.

A preferred form ofmy invention and a certain modification thereof are shown in the drawings in which- Fig. 1 is a side elevation of my improved bobbin support.

Fig. 2 is a top plan view of the bobbin support;

Fig. 3 is a sectional elevation taken along the line 33 in Fig. 2;

Fig. 4t is a sectional elevation of a modified form of bobbin support," and Fig. 5 isfa side elevation of the parts shown in Fig. a, looking in the direction of the arrow 5 in said figure.

Referring to Figs. 1 to 3, the yarn'Y is drawn from the bobbin B, passes through guiding and tension devices, and is thereafter wound upon the spool S. The bobbin B and the guiding andtension devices are supported on a stand formed in two parts 1G and 11, which are secured to a supporting bar 12 by a clamping bolt 13. The bar 12 extends the entire length of the machine and suitable mechanism is provided for causing relative vertical movement between the bar 12 and the spools S. It will be understood that a plurality of bobbins and guiding and tension devices are thus mounted in spaced relation upon the bar 12, corresponding in number to the-spooler spindles. Spoolcr guides 14 of any usual type are also clamped to the bar 12 to guide the yarn Y to the spools S and to prevent the passage of snarls and bunches.

A bracket 15 is adjustably secured to each stand 10, extending downward and then latterly. and carrying the support for the bobbin B. Saidbobbin support comprises a dead spindle 20 having a broad flat head 21 formed at its lower end. The head 21 fits loosely within a cylindrical recess 22 in a base 23 which is secured to the bracket 1.5 by screws 24.v The spindle 20 extends upward through a slot 25 (Fig. 3) formed in the upper side of the base and is retained in upright position therein by a coil spring 26 which seats the head 21 firmly upon the portion of the bracket 15 which underlies the recess 22. The slot 25 is so disposed that the spindle can be swung forwardas indicated in dotted lines in Fig. 3, but is prevented from movement in any other direction. A guide eye 27 of usual form is adjustably clamped to a lug 28 formed on the stand 10.

By the use of the swinging dead spindle I am able to position the eye 27 much closer to the upper end of the bobbin B than would otherwise be possible, as the spindle may be swung forward out of alinement with the guide eye when it is desired to insert a bobbin, or to remove a bobbin therefrom. By thus placing the guide eye closely adjacent to the end of the bobbin I reduce the ballooning of the yarn and can use higher speed and closer spacing than would otherwise be practicable.

In Figs. and 5 I have shown a modified form of the bobbin support shown in Figs. 2 and 3, and previously described. In Figs. I and 5, the base member St) is formed of sheet metal having downwardly projecting lugs 8l8l fitting in notches 82 in the sides of the bracket 15, and adapted to be bent beneath the bracket to permanently retain the base member in position. I also provide a slot 83:5 in the bracket 15, extending in the opposite direction from the slot .84 in the top of the base member. The spindle 85 is extended below the head 86 and into the slot 83. Lateral displacement of the spindle 85 in one direction is thus more easily accomplished, and the spindle is also more firmly held in normal position. A washer 87 may be placed on the spindle 20, resting upon the base member 80, and supporting the butt of the bobbin. it so desired.

Having thus described my invention and a certain modification thereot. it will be evident that other changes and modifications can be made therein by those skilled in the art without departing from the spirit and scope thereof as set forth in the claims, and I do not wish to be otherwise limited to the details herein disclosed, but what I claim is 1. In a winding machine, a bobbin support comprising a dead spindle having a head, a support for said spindle against which said spring for yieldingly pressing said head against said support and permitting manual sidewise angular displacement of said spindle from normal operative position.

2. In a winding machine, a bobbin support comprising a dead spindle having a head, a support for said spindle, a spring effective to press said head into normal engagement with said support but permitting head is normally seated, and a yielding displacement thereof, and means preventing such displacement except in a single direction.

3. In a winding machine, a bobbin sup port comprising a dead spindle having a head, a supporting casing for said spindle having a recess for said head, and a spring confined in said recess and engaging said head on the upper side thereof, said casing having a slotted opening in its upper face permitting lateral displacement of said spindle in one direction only.

4- In a winding machine, a bobbin support comprising a dead spindle having a head, an inverted cup-shaped base having a slot in its upper face through which said spindle extends, a plate supporting 'said base and retaining said spindle within the base, and a spring encircling said spindle and positioned between the upper part of the base and the head of the spindle, thereby normally seating said head against said plate.

In a winding machine, a bobbin support comprising a headed spindle, a hollow base member within which the head is received, and a support for the base member, said base being slotted on one face to permit displacement of said spindle in one di rection only, and a spring being inclosed within said base effective to yieldingly seat the head of the spindle on the support.

6. In a winding machine, a bobbin support comprising a spindle, an inverted base member, a supporting plate, and a spring normally retaining said spindle in upright position, said base and plate each l'iaving an opening therein through which said spindle extends and being slotted in opposite directions from said openings to permit temporary displacement of the spindle from normal position in one direction only.

7. In a winding machine, a bobbin support comprising a notched plate and an inverted cup-like sheet metal base member secured to said plate, said member having lugs extending into the notches and adapted to be bent beneath said plate. I

8. In a winding machine, a bracket, a dead spindle movably mounted thereon, and a spring holding said spindle normally in operative position but permitting manual sidewise angular displacement of said spindle and automatically restoring said spindle to normal position.

In testimony whereoi I have hereunto at- .fixed my signature.
